techGetSpacingRuleTable

techGetSpacingRuleTable(
d_techID 
t_constraintName 
tx_layer1 
[ tx_layer2 ]
) 
=> l_tables / nil

Description

Returns the table data for the specified constraint defined in the specified technology database and applied to the specified layer or layers. ASCII technology file location: spacingTables subsection in the foundry constraint group.

Arguments

d_techID	The database identifier of the technology database.
t_constraintName	The name of the spacing constraint.
tx_layer1	The first layer on which to apply the table constraint. Valid values: The layer name, the layer number
tx_layer2	The optional second layer on which to apply the table constraint. Valid values: The layer name, the layer number

Value Returned

l_tables

A list defining the table entries. The list has the following syntax: ( ( l_indexDefinitions ) l_table ) where, l_indexDefinitions is a list naming the table indexes. This list has the following syntax: ( nt_index1Name nil nil [ nt_index2Name nil nil] ) where, nt_index1Name is the name of the first dimension of a two-dimensional table or the only dimension of a one-dimensional table and nt_index2Name is the name the second dimension of a two-dimensional table. l_table is a list of the table entries.

nil

The technology database does not exist or there are no spacing tables defined for the specified constraint on the specified layer or layers.
